The newest complication at night in MK is that, in addition to Main St. Electrical Parade and Wishes,
Disney has added
Celebrate the Magic, a show that is actually projected on the castle front facade. In order to be fully enjoyed, guests must be in a position to clearly see the front of the castle (which means be either IN the Hub, or at least along the northern sections of Main Street.)
CtM starts 15 minutes before Wishes and is considered by many to be more spectacular and fun than MSEP or Wishes.
CtM will cause the Hub to be JAMMED with guests by the time MSEP passes through the Hub.
By running THREE evening spectaculars (at least two of which require a viewing spot in or very near the Hub) Disney has now created an intense bottleneck for guests interested in seeing the shows.
BTW, the upper level of the Main Street railroad station is a spectacular place to view
MSEP.
But, it is a relatively poor location to view
Wishes, and a terrible location to view
CtM.
